Laplace Azimuth The Laplace azimuth (geodetic azimuth) of a point in space is equal to the dihedral angle between the plane of the geodetic meridian of the place of observation and the plane that passes through the normal to the surface of the reference ellipsoid at this place and the observed point.aplace Azimuth. the geodetic azimuth A of the direction to an observed point obtained from its astronomical azimuth a corrected by taking into account the effect of the deviation of the vertical at the place of observation.

Geographic coordinate system The latitude (abbreviation: Lat., φ, or phi) of a point on the Earth's surface is the angle between the equatorial plane and the straight line that passes through that point and through (or close to) the center of the Earth.

- All coordinates are given in the WGS 84 coordinate reference system. WGS 84 is the latest revision of the World Geodetic System, which is used in mapping and navigation, including GPS satellite navigation system (the Global Positioning System). Geographic coordinates (latitude and longitude) define a position on the Earth's surface. Coordinates are angular units. The canonical form of latitude and longitude representation uses degrees (°), minutes (′), and seconds (″). GPS systems widely use coordinates in degrees and decimal minutes, or in decimal degrees. Latitude varies from −90° to 90°. The latitude of the Equator is 0°; the latitude of the South Pole is −90°; the latitude of the North Pole is 90°. Positive latitude values correspond to the geographic locations north of the Equator (abbrev. N).

Latitude This is the definition assumed when the word latitude is used without qualification. The definition must be accompanied with a specification of the ellipsoid. Geocentric latitude: the angle between the radius (from centre to the point on the surface) and the equatorial plane. (Figure below).

Geodetic Datums By Amanda Briney, Geography Intern. A geodetic datum is the tool used to define the shape and size of the earth, as well as the reference point for the various coordinate systems used in mapping the earth. Throughout time, hundreds of different datums have been used-each one changing with the earth views of the times.

Definitions &Translations The vector from an observer (origin) to a point of interest is projected perpendicularly onto a reference plane; the angle between the projected vector and a reference vector on the reference plane is called the azimuth. An example is the position of a star in the sky. The star is the point of interest, the reference plane is the horizon or the surface of the sea, and the reference vector points north. The azimuth is the angle between the north vector and the perpendicular projection of the star down onto the horizon.

Test 3 (Final) 1. [Of distance estimation] Using a magnetic compass and a map for distance estimation in order to determine your position. 2. [Of intersection] A method used to determine the location of a distant feature by locating your map position, sighting on the distant feature, and recording the foresight azimuth as noted on a compass. 3. [Of map orientation] Using a compass and a map that shows the direction of magnetic north to orient a map. 4. [Of resection] Using a compass, rather than a straightedge or visual sighting, to determine the back azimuths in the resection method of locating position.

Geodetic datum A Geodetic datum or geodetic system is a coordinate system, and a set of reference points, used to locate places on the Earth (or similar objects).n approximate definition of sea level is the datum WGS 84, an ellipsoid, whereas a more accurate definition is Earth Gravitational Model 2008 (EGM2008), using at least 2,159 spherical harmonics.

- Tilt/Latitude extended definition. Latitude is a measure of the distance you are located from the equator. It is commonly shown as an imaginary horizontal line that goes across the earth on maps and is used along with longitude as a reference point to determine location. The tilt of the earth affects the seasons we experience throughout the year.

What is a datum? A geodetic datum is an abstract coordinate system with a reference surface (such as sea level) that serves to provide known locations to begin surveys and create maps. In this way, datums act similar to starting points when you give someone directions.atums are the basis for all geodetic survey work. Near coastal areas, mean sea level (and other tidal datums) is determined by analyzing observations from a tide gauge. This image shows a tide gauge at the St. Charles Parish Water Level Monitoring System in Louisiana.

Compass Depending on where the compass is located on the surface of the Earth the angle between true north and magnetic north, called magnetic declination can vary widely with geographic location. The local magnetic declination is given on most maps, to allow the map to be oriented with a compass parallel to true north.The Earth's magnetic fields are constantly changing which is referred to as geomagnetic secular variation.requently, in addition to the rose or sometimes instead of it, angle markings in degrees are shown on the compass. North corresponds to zero degrees, and the angles increase clockwise, so east is 90 degrees, south is 180, and west is 270.

Astronomical Coordinates Declination (delta): angular distance from the celestial equator (+=north, -=south). Right Ascension (alpha): angular distance along circles parallel to the equator. Define zero point to be the vernal equinox, the point where the Sun's position crosses the celestial equator as it moves north. Right ascension increases going eastward. Dec is measured in degrees, minutes of arc, seconds of arc, or decimal degrees.
